title: [Endoscopic diagnostics and treatment of submucous tumors of the upper gastrointestinal tract].
abstract: The endoscopic ultrasonography (EUS) is considered to be the leading method of diagnostic of the submucous gastrointestinal tumors. Results of diagnostics and treatment of submucous tumors of the upper gastrointestinal tract in 38 patients were analyzed. EUS was performed in 37 (97,4%) of patients, which allowed to detect the origin, size and localization of the tumor. The differential diagnostic algorithm was suggested together with certain indications for various surgical treatment modalities. Thereby, endoscopic ablation is reasonable when the tumor invades not deeper than muscle plate of mucosa or the submucose layer. Laparoscopic full-layer resection of the organ wall is necessary when the tumor invades the muscle layer. Larger tumors or those of any size, but with preoperative signs of high malignancy must be eradicated through laparotomy, meeting all principles of oncology.
